Description

Technical Field

[0001] This invention relates to the field of wind tunnel experimental simulation technology, specifically to a three-dimensional wind tunnel simulation device, system, and method for the entire evolution process of tropical cyclones. Background Technology

[0002] Tropical cyclones, as extreme weather phenomena, can cause significant damage to urban construction and economic development. To minimize the losses caused by tropical cyclones, structural wind-resistant design is essential. Wind tunnel testing is one of the most important research methods in structural wind engineering. Compared to field measurement methods, wind tunnel testing is more economical in terms of manpower, resources, and time, and allows for the artificial control and modification of test conditions. Therefore, it has significant advantages in conducting mechanistic studies considering the influence of variable parameters and solving complex engineering problems. However, due to limitations in the simulation capabilities of existing wind tunnel testing equipment and the inability to fully meet similar parameters, wind tunnel testing methods also have certain limitations, such as the inability to accurately reflect the wind field characteristics of tropical cyclones. Therefore, installing a device capable of simulating the three-dimensional wind field throughout the entire evolution of a tropical cyclone in the test section provides a novel experimental means for analyzing structural loads and response characteristics under tropical cyclone action, which is of great significance for meeting structural wind resistance requirements. Summary of the Invention

The two ends of the horizontal blades are rotatably connected to the two left and right columns respectively, and the top of the vertical blades is connected to the top beam and the bottom is connected to the base.

[0006] The transverse blade includes a blade base and multiple turntables embedded in the blade base, with the turntables rotatably connected to the blade base;

[0007] The multiple turntables are arranged in a row on the blade base, and the turntables on each transverse blade are aligned in the vertical direction to form a turntable array; in the turntable array, all the turntables in a column correspond to a vertical blade, and the turntables on the transverse blades are provided with slots to allow the vertical blades to pass through.

[0008] The drive mechanism includes multiple first drive motors and multiple second drive motors, wherein: the first drive motors correspond one-to-one with the transverse blades and are used to drive the transverse blades to pitch and rotate; the second drive motors correspond one-to-one with the turntables and are used to drive the turntables to rotate, thereby causing the vertical blades to twist at the corresponding height positions.

[0009] Based on the above solutions, further improvements or preferred solutions include:

[0010] Furthermore, the top beam or base is fitted with a turntable corresponding to each vertical blade. The turntable on the top beam or base is rotatably connected to the base of the top beam or base, and the turntable on the top beam or base is also driven to rotate by the second drive mechanism.

[0011] Furthermore, the turntable has a toothed structure on its periphery, and the second drive motor is installed on the side of the turntable, driving the turntable to rotate through a gear transmission structure that meshes with the toothed structure.

[0012] Furthermore, the vertical blades are made of elastic material strips that expand and contract with the rotation of the corresponding turntable.

[0013] Furthermore, the vertical blade is a flexible material strip, one end of which is connected to the top beam or base via a reel. The reel is used to release or retract the vertical blade, and is connected to a tension adjustment mechanism installed on the top beam or base. The tension adjustment mechanism is used to control the rotation of the reel.

[0014] Furthermore, the tension adjustment mechanism is a spring or a third drive motor connected to the control system.

[0015] Furthermore, the vertical blade includes two vertical blade layers and a spring layer sandwiched between the two vertical blade layers.

[0016] A three-dimensional wind tunnel simulation system for the entire evolution of a tropical cyclone is characterized by comprising a wedge structure, a simulation device, a rough structure, and a wind speed sensor group arranged sequentially along the airflow direction.

[0017] Furthermore, the three-dimensional wind tunnel simulation system for the entire evolution of tropical cyclones also includes a wind tunnel floor parallel to the horizontal plane;

[0040] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0041] Example 1:

[0042] like Figure 2 The device shown is a three-dimensional wind tunnel simulation device for the entire evolution process of a tropical cyclone. It consists of a vertical blade structure, a horizontal blade structure, a support structure, a drive mechanism, and a control system. The control system controls each drive mechanism based on the control program and user-input instructions or parameters.

[0043] The vertical blade structure consists of multiple vertical blades 104 arranged in a row, and the horizontal blade structure consists of multiple horizontal blades 105 arranged in a column. The driving mechanism includes multiple first drive motors and multiple second drive motors. The first drive motors correspond one-to-one with the horizontal blades 105 and are used to drive the horizontal blades 105 to pitch and rotate. The second drive motors correspond one-to-one with the turntables 105-1 and are used to drive the turntables 105-1 to rotate, thereby causing the vertical blades 104 to twist at corresponding height positions.

[0044] The aforementioned support structure includes a top beam 101, a base 103, and columns 102 located on the left and right sides of the transverse blade structure. The two ends of the transverse blade 105 are rotatably connected to the two columns 102 via shafts and are driven to rotate by a first drive motor (not shown) installed on either side of the column 102.

[0045] The transverse blade 105 includes a blade base 105-2 and a plurality of turntables 105-1 mounted on the blade base 105-2, wherein the plurality of turntables 105-1 are arranged in a row on the blade base 105-2. Figure 2 Corresponding to each turntable 105-1, the turntable base 105-2 can be divided into multiple rectangular base units. Each base unit is a hollow box-like structure with a circular hole in the center of its upper and lower surfaces. The turntable 105-1 is a gear disk structure, including a disk and toothed structures located on the periphery of the disk. The thickness of the disk is basically the same as the thickness of the base unit, allowing its upper and lower surfaces to remain flush. The diameter of the disk matches the diameter of the circular hole on the base unit, so that the disk fits perfectly into the circular hole. The toothed structure is located at the middle position in the thickness direction of the disk, and its thickness is less than the thickness of the disk. When the disk is fitted into the circular hole, the toothed structure is hidden within the cavity of the base unit. A second drive motor controlling the rotation of the turntable 105-1 is installed beside the turntable 105-1. The second drive motor is located within the cavity of the base unit, and its power output shaft drives the turntable 105-1 to rotate through a gear transmission structure. Figure 4 As shown. The turntable 105-1 has limited freedom of movement in the horizontal and vertical directions, and can only rotate within the blade base 105-2. In practice, if it is necessary to further reduce the friction of the turntable 105-1 during rotation, multiple balls can be arranged on the inner edge of the tooth structure. These balls are evenly distributed around the outer periphery of the disc, and an annular track is provided on the upper and lower surfaces of the base unit cavity. The annular track is located around the circular hole and is concentric with the circular hole. The upper and lower ends of the balls are fixed and installed in the corresponding annular track, so that the turntable 105-1 can rotate while its freedom of movement in other directions is limited.

[0046] In this embodiment, a turntable 105-1 is also embedded in the base 103. The base 103 includes a base body and a plurality of turntables 105-1 mounted on the base body. The turntables 105-1 on the base 103 have the same structure as the turntables 105-1 on the transverse blades 105. The length and width dimensions of the base body are larger than those of the transverse blades. A cavity is also provided at the position where the turntables 105-1 are mounted, and a second drive motor for driving the corresponding turntables 105-1 to rotate is installed in the cavity.

[0047] Each horizontal blade 105 and the turntable 105-1 on the base 103 are aligned vertically to form a turntable array. In the turntable array, each turntable 105-1 in a row corresponds to a vertical blade 104. Each turntable 105-1 has a slot through which the vertical blade 104 passes, and the extension direction of the slot is consistent with the radial direction of the disc. The top of the vertical blade 104 is connected to the horizontally extending top beam 101. The base body has a base plate below the turntable 105-1 on the base 103. The bottom end of the vertical blade 104 passes through the slot and is fixedly connected to the base plate of the base body.

[0048] The vertical blade 104 is a windbreak made of elastic material, which allows it to expand and contract with the torsion of different turntables 105-1.

[0049] Alternatively, in another alternative, the vertical blade 104 can also be a windbreak made of a flexible material, with its top end connected to a reel, which is installed in a pre-set shaft hole on the top beam 101. The top end of the vertical blade 104 is wound onto the reel, which is controlled by a tension adjustment mechanism. The tension adjustment mechanism can be an adaptive adjustment mechanism or an active adjustment mechanism. The adaptive adjustment mechanism is a torsion spring or a spiral spring, etc. When the vertical blade 104 is stretched compared to its initial vertical state, the adaptive adjustment mechanism, which is connected to the reel drive, provides an elastic restoring force to the reel to keep the vertical blade 104 always in a taut and straight state. The active adjustment mechanism is a drive motor, defined as the third drive motor. The control system calculates the pitch angle of the transverse blade 105 and the rotation angle of the turntable 105-1 based on the operating parameters of the first and second drive motors, thereby inferring the release or retraction amount of the corresponding vertical blade 104. The third drive motor controls the rotation of the reel to complete the release or retraction of the vertical blade 104, so that the vertical blade 104 remains taut.

[0050] Example 2:

[0051] In the device of this invention, both the vertical blade 104 and the horizontal blade 105 are airflow obstruction and guidance structures. The horizontal blade 105 can be made of rigid material and can withstand higher wind pressure compared to the vertical blade 104. The vertical blade 104, however, is made of elastic or flexible material and is more prone to deformation under certain wind pressure compared to the horizontal blade 105. To improve the stiffness of the vertical blade 104, this embodiment further improves the structure of the vertical blade 104 based on Embodiment 1.

[0052] In this embodiment, the vertical blade 104 is a composite structure of elastic and flexible materials, consisting of two windbreak strips made of flexible material and a spring layer 104-1 sandwiched between the two windbreak strips. The spring layer 104-1 is composed of multiple parallel steel tension springs, with the top ends of the springs fixedly mounted on the top beam 101 and the bottom ends fixed to the base. The bottom ends of the two windbreak strips are fixed to the base, and their top ends are each wound onto a spool. The two spools are controlled by a tension adjustment mechanism, the selection and design of which are the same as in Embodiment 1, and will not be repeated here.

[0053] Because rigid material springs have better stiffness than flexible material springs, when turntable 105-1 rotates, spring layer 104-1 can provide enhanced rigid support for the windbreak strip on the windward side.

[0054] When the vertical blade 104 is parallel to the airflow direction, the pressure-bearing area is small, making it less prone to deformation in the airflow direction. However, to avoid the airflow passing between the two wind deflectors significantly affecting their parallelism under high air pressure, a vertical baffle can be installed at the center of the turntable 105-1, with one baffle corresponding to one row of turntables 105-1. The top end of the baffle is fixed to the top beam 101, and the bottom end passes through the turntable 105-1 and is fixed to the base. Each stop lever has a ball joint 105-3 at the height position corresponding to each transverse blade 105. The center of the turntable 105-1 has a ball socket structure with openings at the top and bottom. The ball joint 105-3 is embedded in the ball socket structure, with its top and bottom ends protruding from the openings of the ball socket. The ball socket structure can rotate in multiple directions relative to the ball joint 105-3. The length and width dimensions of the stop lever are smaller than the diameter of the ball joint. After the stop lever passes through the center of the ball joint, it does not contact the turntable 105-1. Therefore, the turntable 105-1 can pitch and rotate within a certain angle range without being interfered with by the stop lever.

[0055] The design gap extends outward from the rear side of the baffle, and the width of the baffle is not less than the width of the gap. In the initial state, when the vertical blade 104 is parallel to the airflow direction, the gap between the two windshields can be blocked by the baffle.

[0056] Example 3:

[0057] like Figure 1 The three-dimensional wind tunnel simulation system for the entire evolution of a tropical cyclone shown includes a wind tunnel floor parallel to the horizontal plane and a wedge structure 2, a simulation device 1, a rough structure 3, and a wind speed sensor group 4 arranged in sequence.

[0058] The wedge structure 2 consists of multiple pyramidal elements arranged in a row, with the pyramidal elements standing upright on the wind tunnel floor with their tips pointing upwards.

[0059] The simulation device 1 adopts the simulation device described in Embodiment 1. It is erected on the wind tunnel floor by a base. The row direction of its turntable array is horizontal in the horizontal plane, and the column direction is vertical in the direction perpendicular to the horizontal plane.

[0060] The rough structure 3 consists of an array of rough elements laid on the wind tunnel floor, wherein the row direction of the rough element array is the horizontal direction of the horizontal plane and the column direction is the vertical direction of the horizontal plane.

[0061] The wind speed sensor group 4 consists of multiple wind speed sensors arranged vertically at equal intervals, and the signal output terminals of the wind speed sensors are connected to the control system.

[0062] The pitch angle of the transverse blade 105 of the simulation device is defined as... The corresponding first drive motor is individually controlled through the programming software of the control system, thereby adjusting... Size, The value range is generally from -60° to 60°. When the angle of the transverse blade 105 is 0°, it is parallel to the ground (i.e., the horizontal plane). When the simulation system is working, by adjusting the angle of the transverse blade 105, the requirements for simulating different wind speeds and directions can be met, so that the airflow after passing through the transverse blade structure can reflect the time-varying characteristics of tropical cyclones.

[0063] The torsional angle of the vertical blade 104 of the simulation device is defined as... The corresponding second drive motor is individually controlled through the programming software of the control system, thereby adjusting... angular size, The value range is from -90° to 90°. When the torsion angle of the vertical blade 104 at different heights is 0°, the vertical blade 104 is perpendicular to the ground (i.e., the horizontal plane). When the simulation system is working, by adjusting the angle of the vertical blade 104, the system can change the mean wind profile and the direction of airflow in the wind tunnel, or in other words, it can achieve the function of synchronously changing the mean wind profile and the wind direction at different heights.

[0064] The process of using the aforementioned simulation system to perform a three-dimensional wind tunnel simulation of the entire evolution of a tropical cyclone is as follows:

[0065] S1. Lay a wind tunnel floor parallel to the horizontal plane, and arrange the wedge structure 2, simulation device 1, rough structure 3 and wind speed sensor group 4 of the simulation system in sequence on the wind tunnel floor, with the wedge structure 2 located upwind in the airflow direction.

[0066] S2: Start the airflow output device to deliver airflow to the simulation system, so that the airflow passes through the wedge structure 2, the simulation device 1, the rough structure 3 and the wind speed sensor group 4 in sequence.

[0067] S3. The control system collects the wind speed data fed back by each wind speed sensor, obtains the wind profile (or wind speed profile) at the location of the sensor, and determines whether it conforms to the target wind profile.

[0068] If the conditions are met, subsequent wind tunnel tests on the wind profile effect will be conducted.

[0069] If it does not meet the requirements, the corresponding drive motor is started to adjust the pitch angle of the horizontal blade 105 or the torsion angle of the vertical blade 104 at the corresponding height in real time, so that the wind profile formed at the current time conforms to the target wind profile.

[0070] Figure 6 The diagram shows the wind direction angle and corresponding wind speed of a tropical cyclone simulated using three different schemes.

[0071] Figure 7 To adjust the wind angle of attack using a simulation device Guide angle After calculating the wind speed, the results were normalized to obtain a comparison chart with the average wind profile of the actual typhoon. The left chart is Scheme 2 (simulating the outer strong wind area), and the right chart is Scheme 3 (simulating the eyewall area).

[0072] In the figure: the horizontal axis represents the wind speed ratio, which is the ratio of the wind speed at height Z to the wind speed at the reference height (the reference height is selected as the height H corresponding to the strongest wind speed); the vertical axis represents the height ratio, which is the ratio of the height at Z to the height corresponding to the strongest wind speed.

[0073] Figure 8 yes Figure 7 The diagram shows the state of the simulation device when simulating the wind attack angle and guide angle in the outer strong wind zone and eyewall zone. The left figure is Scheme 2 (wind speed 10m / s, guide angle 23°, angle of attack from bottom to top: 0°, 0°, 40°, 0°, -40°), and the right figure is Scheme 3 (wind speed 15m / s, guide angle 40°, angle of attack from bottom to top: 0°, 4.5°, 0°, 31°, -36°).

[0074] Figure 9 The diagram below shows the state of the simulation device and the corresponding wind profile in Scheme 1 (wind speed 5m / s, guide angle 15°, angle of attack from bottom to top: 0°, -15°, 15°, -30°, 0°).

All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should be considered within the scope of protection of the present invention.
